Release 0.0.8

This release changes the usability of the program - basically, the printing function works slightly better with line numbers, and many functions have been re-written to simplify the implementation, optimize a few edge cases, provide more robustness... and now you can insert/move/copy stuff past the end of the buffer, instead of needing to do it line-by-line. :)

I also changed the way I passed around readers and writers.

All in all, the positive changes measured a net loss in binary size, woohoo!
